Duncan,
        Forget Mg where there is almost no established traditional usage.
7.5 tons (where one ton is *defined* as 1000 kg) is much better for *large
multiples of the SI unit of mass (kg)*, in accord with established usage.
        Only for small submultiples of mass, e.g. for a few milligrams or
micrograms, are prefixes applied to g (gram) preferable (where there is
also long established usage).
